TREATMENT OF SWAGE IN SANITARY CLOSETS.

y Application ined December 7, 1927,y serial Nq. 238,310, and in exea/tamtam December 2o, i926.

tovbecome splashed with the disinfectingY liquid contained in the tank.

The object vof the present invention is to overcome this inconvenience.

According to the present invention a shield l is normally located beneath the basin and prevents splashing. Such vshield is fixed upon a spindle, whichalso carries the means for breaking up the sewage. Means are provided for oscillating and rotating thel spindles suficiently to cause the-shield and the device for breaking up the sewage to eiiterthe disinfectant and to thereby become cleansed. The apparatus is so designed that `the shield is normally in the upper position.

The shield maybe in the form of a plate and it may be perforated.V The plate may be of any suitableV form such as convex onits upper surface. V l,

The means for breaking up the sewage may consist of a toothed bar `as in the known type of apparatus.

The shield, in one constructiommay be in the form of a cylinder carried by arms fixed upon the rotating spindle, and part of the cylinder may carry teeth for the purpose of breaking up the sewage. y

The arms may be in the forinof propeller blades, upon one of which is mounted a shield Vin the form of a plate, and in this modifica# tion the shield itself and the ends of the prorentering the chamber m.

y AReferring moreparticularly to Figs. l, 2 and 3, a is thetank having two apertures b, b at the upper partv thereof. ,The dotted line 1 1 indicates the upper surface ofdisinfecting liquid. c, 0 are two bearings A to receive two short spindles d, d on whichfare fixed arms e,-e that carry on their `outer ends angle bars f, f .having pointed teeth. g isa crank attached to the spindles d, d which isconnected by a connecting rody i to a vertically slidngvrod carrying at itsupper Vend the handle z'. Y' VIn the construction shown 4the two bearings c, c are apertures inbars which'arev also NTA OFFICE;-

marked with the lettere, 'l and .'which pass across the tank and are fastened at their ends A by'means of bolt-s y' screwing intothe ends 01 thereof which arei'b/ent at right angles to the main portions, 0. e

The crank g is a two armed crank, each of its arms being connected to'A one of the short spindles d." The' connecting rod h is connected at its upper end tothe lower end of a sliding rod carrying atits upper end the operating handle z'. The rod 7c passes through a guiding tube ll'which, in the lconstructionshown, is carried bythe upper part of a chamber m fixed to the top ofthe tanka. The chamber m allows a long connecting rod l7i to be employed, the upper end of this latter The long connecting rod tallows the crank g and parts carried thereby to be readilyrotated. i' f One of the arms e e is carriedpupwards beyondthe spindled, and is bent intoa horizonta'l position at n. To this part n` is iixeda lll shield o which, as sho-wn in the drawings, is perforated and is curved downwards at the y front and back thereof.

washed clean and disinfected.

The weight of the toothed angle bars f, f is suiiicient to ret-ain theshield o in its upper position and the parts will generally come to rest in this position after the spindles have been rotated. y

As shown in the drawings the two apertures b, are surrounded with short tubes g formed at their upper ends with a suitable flange to receive any usual basin g1 part of which is only shown in the drawings, as such basins are well known. It is assumed in the drawings that only one basin is employed, and the other tube gf is shown closed by means of a cover plate r. It each tube g carries a basin, both of the arms e are carried upwardly and each carries at its upper end a shield 0. A second shield o and parts connected therewith are shown in Fig. 2 in dotted lines.

It will be noticed by referring to Fig. l that thelower arms e, e are set at an angle to each other. These arms e, e are thus tixed upon the spindles d, cl so that the left hand arm e may balance the weight of the crank g and connectingrod h.

In the modified construction shown in Fig. 4 the bearings c, e are arranged at one end of the tank a and the bar 'nis extended and carries at one end a shieldI 0 and at the other end a toothed angle bar f.

The lower part of the arm e carries a balance weight s to normally retain the shield o and the upper toothed angle bar f in the upper position.

If desired the lower part of the arm e may be extended, as shown in dotted lines, and may carry a second toothed angle bar f. This lower toothed angle bar f shown in dotted lines, willr probably weigh sufficient to act as a balance weight, and will retain the shield o andthe upper toothed bar f normally in their upper positions ready for use.

In the modification shown in Fig. 5 the shield 0 and the toothed angle bar f have been replaced by a drum t the upper part of which is perforated and acts in the same manner as the shield o, and the lower part of which is provided with teeth u which act like a v toothed bar f to break up the sewage contained withinthe tanken.`

In this construction, should the drum not return to the position shown in Fig. 5, some other part of the drum will be located beneath the aperture b and will act as a shield. The drum t is shown as being carried by arms o which are equivalent to the arms e shown in Figs. 1, 2 and 3. In this modiicat-ion the drum t and arms c provide means for connecting' and supporting the upper part of the drum acting as a shield and the lower part of the drum carrying the teeth u which forms means of the handle t', but the spring 'w will retain the bar f in the upper position if it is rotated by means of the handle z' until it rests within the two ends of the spring fw.

rIhe spring w enables the shield o always to be retained in its top position even should the parts get unbalanced due to sewage adhering thereto. e

It will be understood that a similar spring w may act in conjunction with one of the toothed angle bars f as shown at the lower part oi Fig. 2. A similar spring w fixed to the end of the tank a would work equally well in conjunction with the vertical rod p as also shown in Fig. 2'.

The method of driving the spindles d, d and crank g by means of a connecting rod 71, and Voperating rod lo, shown in Figs. l, 2 and 3, enables the shield o to be passed beneath the disinfectant inthe tank, but it is diiicult to cause' the spindles cl, cl to completely rotate and it sometimes happens that the parts stop with the crank g on a dead centre, when it is difficult to move the spindles and parts connected therewith.

To obviate this diiiiculty, as shown in Figs. 7 and 9 the crank g may be connected to a rod loo which passes through a ball f/l' mounted in a casing y. This ball y1 allows the rodw to slide therethrough and the ball can oscillate within the casing jz/. At its upper end the rod carries a suitable handle z' which may merely extend on one side oft the rod and be used as a crank handle. With the parts made in the proportion shown in Fig. 7 the handle z' will move approximately in a circular path and will cause the crank g to rotate so long at the handle is being rotated. Should the crank be arrested in alignment with the rod a it can easily be moved by a forward or backward movement of. the handle z'.

As shown in Fig. 8 the shield o is mounted on the end of an arm,which is one blade ya of a screw propeller and as these parts are caused to rotate they will break up the sewage and willmix it with the disinfectant in the tank a, rlhe ends of the blades .a act as teeth and cut and break up the solid parts of the sewage like the toothed bars f and the teeth u.
